When a fan takes part, or reads their own vote or messages, add their token from your own login as `Authorization: Bearer `. **Names.** An experience is one thing fans take part in: a poll or a Fan Voice. A collection groups experiences for a match or show, and an experience can be in many collections. Every ID is a UUID: store it in a UUID column or as text, and never parse it. **Conventions.** snake_case fields; `after` and `limit` paging (50 by default, 100 at most) with `{items, next}`; errors are RFC 9457 problems with a stable `code` and a `request_id`, and every response carries `x-request-id`. Types, statuses and codes can gain values within v1, so ignore one you don't know. **Refreshing.** Read an open poll every 10 seconds and lists every 30 seconds, and wait as long as `Retry-After` says after a `429` or `503`. The Experiences guide has the details. contact: name: Dizplai servers: - url: https://api.dizplai.com/v1 description: The Dizplai API. security: - apiKey: [] tags: - name: Experiences description: >- Everything fans can take part in, in one list: build a match or show screen from it, drawing each experience by its type. - name: Collections description: >- Groups of experiences, one for each match or show, to organise your screens.
